Perhaps you should try some spelling variations:
"parameters optimization algorithmssssssssss" » "parameter optimization algorithmssssssssss", "parameter estimation algorithmssssssssss", "parameters optimization algorithmsssssssssss", "parameters optimisation algorithmssssssssss", "parameters estimation algorithmssssssssss"
"allocation optimization algorithm" » "allocation optimization algorithms", "allocation optimisation algorithm", "allocation estimation algorithm", "location optimization algorithm"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("allocation optimization algorithm") or ("parameters optimization algorithmssssssssss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("allocation optimization algorithm") OR ("parameters optimization algorithmssssssssss")).
• Removing quotes may allow a broader search: (( allocation optimization algorithm ) or ( parameters optimization algorithmssssssssss )).
• Adding a wildcard symbol may retrieve word variants: (("allocation optimization algorithm") or ("parameters optimization algorithmssssssssss"))*.
